Foldable Central-Leg Railway Table for Easier Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing removable tables for public transport vehicle compartments are cumbersome and require two operators for relocation, posing a risk of damage during transport due to congestion and potential impacts with other compartment elements.
Innovation Solution
A removable table design featuring a pivot-connected central leg that folds back for easier handling, a supporting member with rollers or shoes for floor support, and maintaining members to stabilize shelves, allowing single-operator transport and reduced risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the table is designed with a fixed central leg for stability, then the table provides adequate support, but the table becomes cumbersome and requires two operators for displacement
Solution Approach 1:
The central leg is made dynamic through a pivot connection that allows it to switch between an extended stable position during use and a folded position during transport. This dynamic transformation enables the table to adapt its structure based on operational requirements, resolving the contradiction between stability and ease of displacement.
2Device complexity
If the table is designed with a fixed central leg, then the table structure is simple, but the table risks impacting against other compartment elements during transport
Solution Approach 1:
The pivot connection enables the central leg to be folded during transport, reducing the table's overall dimensions and minimizing the risk of impact with other compartment elements. This dynamic adjustment allows the table to adapt its configuration to avoid harmful interactions during movement.
3Ease of operation
If the central leg is made foldable via pivot connection, then the table becomes easier to handle and transport, but the table structure becomes more complex
Solution Approach 1:
The pivot connection provides a simple yet effective mechanism for folding the central leg, enabling easy transformation between extended and folded positions. This dynamic element adds minimal structural complexity while significantly improving handling and transport ease.

AI summary
The table (10) includes a plate (12) extending, in a longitudinal direction, between a first lateral edge (12A) bearing first removable attachment elements (14) to a lateral wall of the compartment, and a second free lateral edge (12B), and a central leg (18) extending between a first end (18A) connected to the plate and a second end (18B) including second removable attachment elements (20) to the floor of the compartment. The first end of the central leg is connected to the plate through a pivot connection (26) allowing pivoting of the central leg for folding it back towards one of the first or second lateral edges of the plate, and the plate includes, at the other one of the first or second lateral edges of the plate, at least one supporting member (28) on which the plate is intended to be supported when the plate is laid on the floor.
